解决无法启动Maven服务问题java.lang.RuntimeException: Cannot start maven service at

1、背景：

下载安装maven，配置环境变量，在idea中设置maven路径，在构建项目时，发现maven启动不成功，然后检查maven路径，maven与idea版本是否兼容，settings文件配置阿里中央仓库也解决不了，这个问题弄了好久，原来是VM参数配置错了，后来在VM options for importer 中添加参数 -Djava.net.preferIPv4Stack=true才解决

2、问题报错信息：maven启动失败

3、问题解决：VM options for importer 中添加参数 -Djava.net.preferIPv4Stack=true ，最后重新构建项目就好了
